Now, I came to know that, one guy in the client place, stole the ERP.FDB and tried several passwords and did not get it, so, he installed a FIREBIRD on his computer and copied the ERP.FDB and opened it with FIREBIRD default password, and stole the entire db design. How to protect from this kind of things ? How to make sure, that the database cannot be copied? Regards & Thanks, Rudy Huang
